Explanation of Responses:

( 1 )Represents securities surrendered to Veeco to satisfy tax withholding obligations due upon the vesting of restricted stock. ( 2 )These shares were acquired pursuant to a restricted stock award under the Veeco Instructions Inc. 2019 Stock Incentive Plan and are subject to certain restrictions. These restrictions will lapse with respect to one-third of such shares on each of the first, second and third anniversaries of the grant date, subject to the reporting person's continued service through such dates. ( 3 )On March 17, 2022, the reporting person was granted the contingent right to receive 16,250 performance-based restricted stock units ("PRSUs"). This contingent right is subject to the reporting person's continued service with the Company and the achievement of three-year performance criteria, which is based on the Company's total shareholder return relative to other companies in the Russell 2000 as specified in the award agreement (the "Criteria"). Each PRSU represents the contingent right to receive one share of Veeco common stock. The award, if earned, could range from 50% to 200% of the granted PRSUs based on the achievement of the Criteria. If the Criteria are not achieved, the award will be forfeited. Subject to having been earned, vested shares will be delivered to the reporting person on the date specified in the award agreement, but in no case earlier than the third anniversary of the grant date.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
